@Jesus . Nice work Man .  I have been building and building and designing feedback circuits by the hand full . If you need any parts like maybe germanium transistors to play with i have 120+ of them i bought off ebay . all different gains and base voltages . i would be glad to send you a bout 5 or 10 for a self addressed soft pack . and i will sort thru them like i have been doing getting the best gain vers bias for our / your low voltage 1.5 volt operation to further increase the positivity of the system for feedback to Source . you interested ?Drop me a pm and ill give you my address . I find this subject interesting because i do have a self runner but want to compact it to a solid state or at least Miniaturize the device to carry and power itself along with doing work . My Bedini weigh self runner weight about 40 pounds total and it ain't that portable   :o  . I hope My endeavorers will eventually help you . God Speed .. Al

I do accept your help. I have been trying to get parts from some part sellers and they all have some excuse for not sending the items I bought. I will PM you for the addresses. I am just tire now. It is 3am here. I am going off for today.
Thanks!!

Jesus

Hi Al,

I wonder if your "self runner" runs by energy created by itself?  Do you mean that or "self runner" only a name ?

Any more details if you can?

Thanks,

Sorry to bump in, but - which "selfrunner" ???
Thanks!

@nievesoliveras
A resistor divider (potentiometer circuit) is widely used, but not for any kind of power intensive (or energy efficient) applications...
It works perfectly with a "high impedance" circuits (like measurement with a Universal digital V-meters...) Or, many High-Ohm electronical applications...

The name says it all. It's a "Voltage divider". It's Not the power divider.... Ohm's law.
Using a different resistor would cause the same theoretical voltage division (300 Ohm/100 Ohm is exactly the same as 300 MOhm/100 MOhm regarding a pure Voltage division...).
But in practice?

So if you want to use an efficient circuit to "match" a higher voltage source to lower voltage "drain" interaction, search for DC/DC down-converter circuits. They're much more efficient than a simple resistor divider (potentiometer) circuits.
Cheers!

I have the step down circuit already, but I need to finish this test plan to the letter to move to that other side of the experiments.

According to plan steps 8, 9 and 10 are accomplished here.

When I tested the circuit with the 4 circuits composition, the leds and the neon bulb, only flicked very faintly. Meaning that there is not strength on the voltage from the coil.
I tried it directly just after the 2n4007 diode and got the same results, just a little brighter.

Even though this experiment has not worked as expected, I have learned a lot doing it. I will make some more tests.

I did not included this circuit on the post I made yesterday at 3am, because the polarity of the transistor is not as usual and I did not dare to change it. Maybe I am wrong here, remember I dont have electronic education, what I know now is gathered while experimenting now.

Your right . My transistor is pnp not npn. i'll correct it . it would be right with the pnp symbol i just wasn't thinking and stuck the first transistor symbol in there ... ???..My head hurts  :-[ Thanks for catching it .You are REal good at that and i admire that about you . I don't believe you about not knowing electronics ;D  I am getting used to a schematic drawing program and i usually draw these things late at night /early like you 3am and about have out of it .. EDIT . ARRRRHHH. Can you delete post . i don't see a delete option . i Think the darn led is reversed now . . anyways i never paid attention to the led symbol either so if the led don't light just reverse it ..feel free to correct any mistakes i made during my Novice drawings ..

@nievesoliver
                     In fact you can eliminate d3 all together . I have to dig that one out of My box of Jts and trace them out again .I know it worked asi  built it but im not sure on drawing it out polarity wise . forgive me . I haven't drawn a schematic in over 25 years . i just read them and build from them . I stick a part in there and if it don't light i reverse it :) i recall that the led is lighting from a non standard location and getting some voltage from the secondary and interfacing with the primary..I used it as an indicator for adjustments...I have to stop putting goop all over them to keep them from shorting out . that was before i got my little project proto board and the soldering pencil was what i used to hold it together . i gave a few to my daughter and made them pendant like so they wouldn't break apart. ;D PLease fix it for replication ... i need to take my meds...

@gadgetmall

You are forgiven. The value in all this is your good intentions. Maybe you are like me that take several circuits and build one from them.
The knowledge of electronics I have are trying to make the bedini motor to feedback. If you notice the first thing that you have to deal with on that circuit is with the npn transistor. Hence I can tell when it is npn or pnp.

I will make the corrections you said and repost it again.

Looking the way the flash circuit has a seven winds coil over the other two. I compared it with @mk1's idea and a light turned on inside my head.
I did this version of a transformer. I took the toroid and added the seven turns of wire over the other winding and connected as the audio transformer is connected. I will let you know what hapened.

I tried all the transistors I have on this transformer and does not work configured as the audio transformer that suppose to go in that place.
By the way, the pot that is supposed to be used, was too big for the space and too difficult to connect, so I used the transistor formula posted before instead.

Edit:
Connected as it is, the LED should light and it is not.

@jesus
 Theres no reason My circuit couldn't work powering your motor and feeding back . If you wind a regular 40 turn Jt  then wind two more secondaries one with 12volts and the other 12volts ,replace the dc converter  and test run the Newman on the Jt output . you will need variable resistor in any circuit you put a load on to tune it for an output .. Have you tried that ? solder some wires on your pot so they can stick in the holes
